Trying to write an itinerary program.
Got date and time from date time picker
Converted it to date variables to extract the date and the time
The form has first a textbox displaying the starting date and time via the
picker.
The next few text boxes allow user input of hours and minutes for elapsed
time of occurring events
Each text box subtracts or adds from the previous box to reveal a new date
time
Example:
The start date is 9/9/2004 2:15:00 AM
I want to subtract 4 hours and 30 minutes (a changeable user input to a
textbox) from the start date and produce a new date time (which is converted
to a string and output to a display).
The problem: How can I get the minutes to borrow from the hours, and the
hours to borrow from the date when that is required.
Also, for the output display, is it typical to use a textbox or a label
control for output results? 10 1778
you don't have to do all that mess
use DateAdd , DateDiff, etc
--but if you're working from text boxes and trying to simulate what vb can
do -
you can use the integer division operator "\" and the "Mod" operator to
divide by 60 and get the remainder

The textbox that gets the user input defaults to the system date unless I
clone the date from the date time picker and either add or subtract the
hours and minutes.
I'm still left with the question: How do I get vb to borrow from the parent
variable values?
All that mess is the form.
Thanks. Could use more input.

This is not as hard as you seem to be making it. Can you post the code that
you have tried?
Well, if it's not as hard as I have been making it, then what is the answer?

A simple answer will suffice.

Hal's suggestion of using DateAdd() and/or DateDiff() was a simple answer.
Since you didn't seem to understand it, I figured you were completely lost
and I wanted to see what path you were going down. However, Tom's answer
seems to have done the trick. I just hope he didn't do your homework for
you.

Hello,
Wondering, if C# (framework 2.0) does not support parsing DateTime timezones
in three letter acronyms.
I would like to parse date strings like "2005 Nov 01 11:58:47.490 CST -6:00"
but it seems C# does not support the timezone letters (CST). I suppose to
use the symbol ZZZ for the timezone letters, but MSDE pointed out that
it is not supported in C#, isn't it?
